MEANS FOROPERATIN 'G POURING-MUZZLE'ST OPPERS IN MOLTEN-METAL LADLES.

Application filed July 9,

My invention relates to molten metal ladles, primarily, at least, for use in open hearth furnaces, and particularly to means for manipulating, operating and controlling the plug or stopper used. to open and close the pouring nozzle..

Obviously, of course, it is essential to the successful operation of a ladle, that the stopper or plug be rigidly maintained in perfect alignment with the pouring nozzle, and also that it be so mounted and secured that it may be operated promptly and with certainty to open and close the nozzle at exactly the proper moment, and to this end it is necessary that the stopper and the mechanlsm by which it is operated and controlled be rigidly, and at the same time freely operatively, connected.

In the accompanying drawings, Fig. 1 is a fragmentary front view showing my device attached to a ladle; Fig. 2 is a similarside view showing the method of mounting and operating the same; and Fig. 3 is a section of bracket 3 on line 33 Fig. 2.

L represents the ladle and securely attached to the ladle, adjacent the bottom, is the bracket 1, provided with the central opening 2.

Further upon the ladle, adjacent the center, is the bracket 3 carrying the oppositely disposed over-lapping flanges 44, thus forming the rectangular guide-way 5 with the central opening.

Still further upon the ladle, adjacent to the top, is the bracket 7 carrying the oppositely disposed overlapping flanges 8-8, thus forming a second guide-way identical with 5.

Sidably mounted'in these guide-Ways is the base or slide 9, carrying at its upper end the right-angle flange 10. i I

Rigidly secured to this slide isthe rod 11, having at its upper and lower ends the extensions 12 and 13, respectively.

Detachably secured to the flange 10 of slide 9, and to the extension 12 of rod 11, by means of bolt 14 and pins 15 and 16, is the horizontal. arm 17 while the extension 13 of rod 11 is slidably mounted inthe opening 2 of bracket 1.

Rotatably and slidably mounted upon the extension 13 of rod 11, and resting upon the top of bracket 1, is the curved bracket 18 provided. with a forked upper or outer end 19, in which is mounted, intermediate its ends, the lever 20, the inner end of which is also forked, each arm of the fork carrying a round head was. sci-m ne. 291,416,

21 which engages the collars 22-22 rigidly carried by the rod 11.

It is obvious that this method of mountin g bracket 18 and the lever makes it possible to economize in space, as the lever 20 may be turned to any radius of rod 11.

Secured to the inner end of arm 17, by means of nuts 23 and 24K, is the rod or stem 25, the lower end of which is secured to the stopper 26 designed to open and close the pouring-nozzle 27.

It will also be observed that this method of connecting the operating rod 11 with the stopper stem 25 avoids all danger or possibility of any loose, swinging or oscillating movement of the stem 25, thus at all times holding it in perfect alignment with the pouring-nozzle 27, which, as already indicated, is one of the essentials in the perfect operation of a ladle.

In operation, when it is desired to cast, as it is termed in mill parlance, the operator simply presses down on the lever 20, which, through the medium of rod 11, arm 17 and stem 25, lifts the stopper 26 from the pouring-nozzle 27 and permits the molten metal to escape into molds placed for its reception.

WVhen so desired, the entire mechanism may be held in any determined position by turning up the screw 28 in bracket 1.

It is obvious that slight modifications may be made in the details of construction, without departing from the scope of the invention, and this applies, perhaps, peculiarly to the connection between the rod 11 and the lever 20.

I claim:

1. In a molten metal ladle having a bottom pouiingnozzle, a perpendicular rod slidably mounted on the outside of the ladle and carrying a pair of stationary collars, a horizontal arm secured to the upper end of said rod and over-hanging the ladle, a depending stem se cured at its upper end to the inner end of said arm, a pouringmozzle stopper secured to the lower end of said stem, a bracket swingingly mounted upon said perpendicular rod, and a lever fulcrumed intermediate its ends to the free end ofsaid bracket and having its inner end adapted to engage the collars on said rod.

2. In a molten metal ladle having a bottom pouring nozzle, a perpendicular rod slidably mounted on the outside of the ladle and carrying a pair of stationary collars, a horizontal anal arm secured to the upper end of said rod and over-hanging the ladle a depending stem se-" cured at its upper end to the inner end of said mounted upon said perpendicular rod a lever :tulerumed intermediate its ends to the free end of said bracket and having its inner end of forked formation, each arm of said fork being adapted to engage said collars.

3. In a molten metal ladle having a bottom pouriugamzzle, a perpendicular base member slidably mounted on the outside of the ladle and carrying a flange at its upper end, a rod rigidly secured to said base member and carrying a pair of stationaryeollars, a horizontal arm secured to the upper end of said rodand to the flange carried by said base et swingingly mounted upon said rod, and a lever fulerumed intermediate its ends to the free-end '01 said bracket and having-lts inner end adap'ted to engagethe collars on said rod. In testimony whereof I have affixed my signature.
